[25] [26] While clockwise spiral staircases are more common in castles than anti-clockwise, they were even more common in medieval structures without a military role, such as religious buildings. [27] The plate armor of European soldiers did not stop soldiers from moving around or necessitate a crane to get them into a saddle.
As of 2024, Dias has had five of his research papers retracted, and five other papers have received an expression of concern. [ 271 ] [ 272 ] Victor Ninov (US), a nuclear chemist formerly at Lawrence Berkeley National Laboratory , was dismissed from his position after falsifying his work on the discovery of elements 116 and 118 .
A system to distinguish papers from "good" and "bad" would be beneficial to researchers. This system may save the reputation of scientists and researchers. Most researchers publish honest work and sometimes simple mistakes happen to be overlooked by the peer review process. Retraction should not be for simple spelling errors, but for inaccurate ...
Other research groups were not able to replicate the results and suggested that impurities in the material led to spurious effects mimicking phenomena associated with superconductivity. Copper(I) sulfide , a compound produced in the synthesis process, turned out to be a close match for the claimed properties of LK-99, and pure samples of LK-99 ...
The misconception was popularized by a 1973 advertising campaign by the St. Regis Paper Company. [65] George Washington Carver was not the inventor of peanut butter. [66] The first peanut butter related patent was filed by John Harvey Kellogg in 1895, and peanut butter was used by the Incas centuries prior to that.
Historical method is the collection of techniques and guidelines that historians use to research and write histories of the past. Secondary sources, primary sources and material evidence such as that derived from archaeology may all be drawn on, and the historian's skill lies in identifying these sources, evaluating their relative authority, and combining their testimony appropriately in order ...

Design errors and mistakes in a microprocessor's hardwired logic may also be documented and described as errata. One well-publicized example is Intel's "FDIV" erratum in early Pentium processors, [7] known as the Pentium FDIV bug. This gave incorrect answers to a floating-point division instruction (FDIV) for a small set of numbers, due to an ...
